Perspectives of physicians and nurses regarding end-of-life care in the intensive care unit.

CONTEXT: The delivery of end-of-life care (EOLC) in the intensive care unit (ICU) varies widely among medical care providers. The differing opinions of nurses and physicians regarding EOLC may help identify areas of improvement. OBJECTIVE: To explore the differences of physicians and nurses on EOLC in the ICU and how these differences vary according to self-reported proficiency level and primary work unit. DESIGN: Cross-sectional survey of 69 ICU physicians and 629 ICU nurses. SETTING: Single tertiary care academic medical institution. RESULTS: A total of 50 physicians (72%) and 331 nurses (53%) participated in the survey. Significant differences between physicians and nurses were noted in the following areas: ability to safely raise concerns, do not resuscitate (DNR) decision making, discussion of health care directives, timely hospice referral, spiritual assessment documentation, utilization of social services, and the availability of EOLC education. In every domain of EOLC, physicians reported a more positive perception than nurses. Additional differences were noted among physicians based on experience, as well as among nurses based on their primary work unit and self-reported proficiency level. CONCLUSIONS: Even with an increased focus on improving EOLC, significant differences continue to exist between the perspectives of nurses and physicians, as well as physicians among themselves and nurses among themselves. These differences may represent significant barriers toward providing comprehensive, consistent, and coordinated EOLC in the ICU.

Resurrecting the Hospital Autopsy: Impact of an Office of Decedent Affairs on Consent Rates, Providers, and Next-of-Kin.

CONTEXT.­: Autopsy rates have decreased dramatically despite providing important clinical information to medical practices and social benefits to decedents' families. OBJECTIVE.­: To assess the impact of an institutional Office of Decedent Affairs (ODA), a direct communication link between pathology and decedents' families, on hospital autopsy consent rates, autopsy-related communication, practitioner views, and next-of-kin experiences. DESIGN.­: A before and after study involving all hospital decedents whose deaths did not fall within the jurisdiction of the medical examiner's office from 2013 to 2018. A pathology-run ODA launched in May 2016 to guide next-of-kin through the hospital death process (including autopsy-related decisions) and serve as the next-of-kin's contact for any subsequent autopsy-related communication. Critical care and hematology/oncology practitioners were assessed for their autopsy-related views and decedents' next-of-kin were assessed for their autopsy-related experiences. Autopsy consent rates for non-medical examiner hospital deaths, autopsy-related communication rates, practitioner views on the role and value of autopsy, and next-of-kin autopsy experiences and decisions factors were compared prior to and after ODA launch. RESULTS.­: Autopsy consent rates significantly increased from 13.2% to 17.3% (480 of 3647 deaths versus 544 of 3148 deaths; P < .001). There were significant increases in the rate of autopsy-related discussions and bereavement counseling provided to decedents' families. Practitioner views on the positive role of autopsy for any hospital death and those with advanced stage cancer also significantly increased. Next-of-kin indicated more consistent autopsy-related discussions with the potential benefits of autopsy discussed becoming key decision factors. CONCLUSIONS.­: An ODA improves hospital autopsy consent rates, autopsy-related communication, providers' autopsy-related views, and next-of-kins autopsy experiences.

Effect of 24-hour mandatory versus on-demand critical care specialist presence on quality of care and family and provider satisfaction in the intensive care unit of a teaching hospital.

OBJECTIVE: The benefit of continuous on-site presence by a staff academic critical care specialist in the intensive care unit of a teaching hospital is not known. We compared the quality of care and patient/family and provider satisfaction before and after changing the staffing model from on-demand to continuous 24-hr critical care specialist presence in the intensive care unit. DESIGN: Two-year prospective cohort study of patient outcomes, processes of care, and family and provider survey of satisfaction, organization, and culture in the intensive care unit. SETTING: Intensive care unit of a teaching hospital. PATIENTS: Consecutive critically ill patients, their families, and their caregivers. INTERVENTIONS: Introduction of night-shift coverage to provide continuous 24-hr on-site, as opposed to on-demand, critical care specialist presence. MEASUREMENTS AND MAIN RESULTS: Of 2,622 patients included in the study, 1,301 were admitted before and 1,321 after the staffing model change. Baseline characteristics and adjusted intensive care unit and hospital mortality were similar between the two groups. The nonadherence to evidence-based care processes improved from 24% to 16% per patient-day after the staffing change (p = .002). The rate of intensive care unit complications decreased from 11% to 7% per patient-day (p = .023). When adjusted for predicted hospital length of stay, admission source, and do-not-resuscitate status, hospital length of stay significantly decreased during the second period (adjusted mean difference -1.4, 95% confidence interval -0.3 to -2.5 days, p = .017). The new model was considered optimal for patient care by the majority of the providers (78% vs. 38% before the intervention, p < .001). Family satisfaction was excellent during both study periods (mean score 5.87 +/- 1.7 vs. 5.95 +/- 2.0, p = .777). CONCLUSIONS: The introduction of continuous (24-hr) on-site presence by a staff academic critical care specialist was associated with improved processes of care and staff satisfaction and decreased intensive care unit complication rate and hospital length of stay.

Histopathologic Findings in Lungs of Patients Treated With Extracorporeal Membrane Oxygenation.

BACKGROUND: The outcome of extracorporeal membrane oxygenation (ECMO) might be influenced by its complications. Only limited information is available regarding the pathologic consequences of ECMO, especially in the era of modern ECMO technology. METHODS: We studied the histopathologic findings in autopsy lungs of patients treated with ECMO compared with those without ECMO. Autopsy files were queried for cases with ECMO. An age- and sex-matched control group comprised of patients who died in the ICU without acute respiratory distress syndrome, pneumonia, or ECMO was compared with patients with ECMO for cardiac reason. Histopathology and medical records were reviewed. RESULTS: Seventy-six patients treated with ECMO (38 men; median age, 40 years) and 47 control patients (23 men; median age, 45 years) were included. Common histologic pulmonary findings in the ECMO group were pulmonary hemorrhage (63.2%), acute lung injury (60.5%), thromboembolic disease (47.4%), calcifications (28.9%), vascular changes (21.1%), and hemorrhagic infarct (21.1%). Pulmonary hemorrhage was associated with longer ECMO duration (median, 7.0 vs 3.5 months; P = .014), acute lung injury with venovenous ECMO (91.7% vs 54.7%; P = .039) and longer ECMO (6.0 vs 4.0 months; P = .044), and pulmonary calcifications with infants (50.0% vs 22.4%; P = .024). Patients with ECMO for cardiac reasons (n = 60) more frequently showed pulmonary hemorrhage (P < .001), diffuse alveolar damage (P = .044), thromboembolic disease (P = .004), hemorrhagic infarct (P = .002), pulmonary calcifications (P = .002), and vascular changes (P = .001) than patients in the non-ECMO group. CONCLUSIONS: Some findings are suspected to be associated with the patient's underlying disease, whereas others might be related to ECMO. Our results provide a better understanding of ECMO-related lung disease and might help to prevent it.

Views of new internal medicine faculty of their preparedness and competence in physician-patient communication.

BACKGROUND: We sought to assess self-rated importance of the medical interview to clinical practice and competence in physician-patient communication among new internal medicine faculty at an academic medical center. METHODS: Since 2001, new internal medicine faculty at the Mayo Clinic College of Medicine (Rochester, Minnesota) have completed a survey on physician-patient communication. The survey asks the new faculty to rate their overall competence in medical interviewing, the importance of the medical interview to their practice, their confidence and adequacy of previous training in handling eight frequently encountered challenging communication scenarios, and whether they would benefit from additional communication training. RESULTS: Between 2001 and 2004, 75 general internists and internal medicine subspecialists were appointed to the faculty, and of these, 58 (77%) completed the survey. The faculty rated (on a 10-point scale) the importance of the medical interview higher than their competence in interviewing; this difference was significant (average +/- SD, 9.4 +/- 1.0 vs 7.7 +/- 1.2, P < .001). Similar results were obtained by sex, age, specialty, years since residency or fellowship training, and perceived benefit of training. Experienced faculty rated their competence in medical interviewing and the importance of the medical interview higher than recent graduates (ie, less than one year since training). For each challenging communication scenario, the new faculty rated the adequacy of their previous training in handling the scenario relatively low. A majority (57%) said they would benefit from additional communication training. CONCLUSION: Although new internal medicine faculty rate high the importance of the medical interview, they rate their competence and adequacy of previous training in medical interviewing relatively low, and many indicate that they would benefit from additional communication training. These results should encourage academic medical centers to make curricula in physician-patient communication available to their faculty members because many of them not only care for patients, but also teach clinical skills, including communication skills, to trainees.

Respiratory failure as the presenting manifestation of amyotrophic lateral sclerosis.

Although amyotrophic lateral sclerosis (ALS) does not directly affect the lung parenchyma, it can jeopardize the mechanical function of the respiratory system. About one-quarter of ALS patients have had at least one prior misdiagnosis. Therefore, a high clinical suspicion, and careful correlation of physical examination and electromyography (EMG) are needed to reach the correct diagnosis. We report a 65-year-old man who presented with a progressive exertional dyspnea. He was subsequently found to have a diaphragmatic paralysis that was felt to be secondary to spinal cord stenosis. However, his subsequent EMG showed evidence of muscle fasciculation and he was ultimately diagnosed with ALS.

Acute tumor lysis syndrome in a patient with mixed small cell and non-small cell tumor.

Tumor lysis syndrome, caused by massive tumor cell death, is an infrequent occurrence in solid tumors, and only a few cases of tumor lysis syndrome occurring in patients with lung cancer have been reported. We present a case of tumor lysis syndrome in a patient with mixed small cell and non-small cell lung cancer complicated by Listeria sepsis. Despite aggressive supportive measures with fluids, electrolytes, antibiotics, pressor agents, ventilation, and alkalinization of the urine, multiorgan failure developed, and the patient died on day 5 in the intensive care unit. Physicians should be aware of this infrequent but potentially fatal complication occurring in critically ill patients with bulky solid tumors so that early and aggressive therapeutic measures can be initiated and appropriate monitoring can be performed.

Practice variability in management of acute respiratory distress syndrome: bringing evidence and clinician education to the bedside using a web-based teaching tool.

BACKGROUND: Clinical practice often lags behind publication of evidence-based research and national consensus guidelines. OBJECTIVE: To assess practice variability in the clinical management of acute respiratory distress syndrome (ARDS) and test an evidence-based, online clinician-education tool designed to improve intensive-care clinicians' understanding of current evidence about ARDS management. METHODS: We surveyed 117 intensive care clinicians (16 critical care physician specialists, 28 resident physicians, 50 critical care nurses, and 23 respiratory therapists) with an online questionnaire in our tertiary academic institution. Fifty of the original respondents (12 residents, 26 critical care nurses, and 12 respiratory therapists) also responded to a repeat survey that included context-sensitive hypertext links to a summary of critically appraised primary articles regarding ARDS management, to determine if the responses changed after the clinicians had read the evidence-based summary information. RESULTS: Critical care physician specialists were most likely to choose the low-tidal-volume (low-VT) ventilation strategy and protocol-based ventilator weaning and were least likely to choose neuromuscular blockade or parenteral nutrition (p < 0.05). In a paired comparison, individual respondents were more likely to choose treatment options that are based on stronger evidence (low-VT, daily interruption in sedation, and protocol weaning [p < 0.01]). We also reviewed the medical records of 100 patients who were mechanically ventilated for > 48 h, during the 6 months before and after the survey, from which we identified 45 ARDS patients. Following the clinician-education intervention, ARDS patients were less likely to receive potentially injurious high-VT ventilation (mean day-3 VT 10.3 +/- 2.3 mL/kg before vs 8.9 +/- 1.7 mL/kg after, p = 0.02). CONCLUSION: Web-based teaching tools are useful to educate intensive-care practitioners and to promote evidence-based practice.

Safety of ultrasound-guided thoracentesis in patients with abnormal preprocedural coagulation parameters.

BACKGROUND: Despite a low incidence of hemorrhagic complications following thoracentesis, correction or attempted correction of abnormal preprocedural coagulation parameters is still commonly performed. We aimed to assess hemorrhagic complications following ultrasound-guided thoracentesis in patients with abnormal preprocedural coagulation parameters. METHODS: We analyzed 1,009 ultrasound-guided thoracenteses performed between January 2005 and September 2011 on patients with international normalized ratio (INR) > 1.6, serum platelet values < 50 × 109/L, or both. Procedures were divided into two groups: those in whom abnormal preprocedural coagulation parameters were not corrected before the thoracentesis (group 1) and a second group in which patients received a transfusion of platelets or fresh frozen plasma prior to thoracentesis (group 2). All procedures were evaluated for hemorrhagic complications as defined by the National Institutes of Health Common Terminology Criteria for Adverse Events. RESULTS: A total of 1,009 ultrasound-guided thoracenteses were included in our study, consisting of 706 procedures in 538 patients in group 1 and 303 procedures in 235 patients in group 2. There were four hemorrhagic complications out of 1,009 procedures (0.40%; 95% CI, 0.15%-1.02%): zero in group 1 (0 of 706 or 0.0%; 95% CI, 0%-0.68%) and four in group 2 (four of 303 or 1.32%; 95% CI, 0.51%-3.36%). CONCLUSIONS: Hemorrhagic complications are infrequent after ultrasound-guided thoracentesis, and attempting to correct an abnormal INR or platelet level before the procedure is unlikely to confer any benefit. We consider the procedure safe in patients with abnormal preprocedural parameters when performed by expert personnel.

Sedation during mechanical ventilation: a systematic review.

OBJECTIVE: A systematic review was performed to determine the most effective agent with which to sedate adult patients who have respiratory failure that requires mechanical ventilation in the medical intensive care unit. DATA SOURCES: A computerized literature search of MEDLINE, a U.S. National Library of Medicine online database, from 1966 to August 1998 was conducted. All selected articles were reviewed to identify other relevant articles. STUDY SELECTION: Inclusion criteria were as follows: a) population-adults with respiratory failure who received mechanical ventilation in a medical intensive care unit; b) design-prospective, randomized controlled trial; c) intervention-sedation; and d) primary outcome-successful sedation. DATA EXTRACTION: Of 71 potentially relevant articles, only 15 randomized trials fulfilled all four selection criteria. DATA SYNTHESIS: Clinical heterogeneity among studies precluded statistical pooling of results. CONCLUSIONS: More research is needed to determine the most effective agent with which to sedate adult patients who have respiratory failure that requires mechanical ventilation in the medical intensive care unit.
